This invention relates to new and useful Iimprovements in gun ports. The objects of thepresent invention are to provide a gunport which is of Simple construction and which is provided with a. elo-vr Sure plate located onl the outer sidev thereof and manually operable from the inner Side whereby said gun port canbe opened only from the interior of the booth or cage and whereby said closure plate when in closed po'- sition cannot be moved or pried open byV a person located outside of said cage.

Other objects of the invention are to provide. a gun port adapted to be Secured within 'tral opening 2O which 1s' preferably tapered an opening formed in a bullet-proof wall and having ya closure plate mounted on the outer Side of said gun port and spring-held in closedposition, said closure plate being so mounted that it canl be moved forwardly to becomef unseated and then laterally to clear lthe opening formedin said gun port.

With these and other objects in view, my

gun port, partly in cross section, and showing .35 the closure plate in open position.

` lteferring by numerals to the accompanying drawing, 10 indicates a bullet-proof wall in the present case formed of non-shatterable fglass. This wall is provided with lan open- 10 ing 11 in which is arrangedfa gun. port 12.

vBriefly thisgun port consists of an outer member 14, an inner member 15, abody .portion 16, and a closure plate 17. f

` The outer member 14 and body portionl are formed integral, member 16 being of j cylindrical shape and fitting loosely into the opening 11.` Y

The-outer member 14 is in the form of a flange which laps over theouter face A of Wall 10. The inner member 15 l is `of ring` flared' `seat 22 in which'is adapted to 'be `of larger diameter than the shank, portion V26a ofsaidbol't., Thus an annular Space is [provided in which is received a coiled spring shape and fits againstV the inner sideBof said wall and is secured to the innery end of body portion V16 by xscrewsl? which latter are" screw-seated in the threaded bores 18gformed in saidbody portion.' Flange 14 and ring 15 are of Vsubstanti ally` the same diameters and serve toV clampthere? i between Vsaid wall 1 0, Athereby Securing` the gun port position within the opening? 11;. Preferably gaskets `19 of felt 4or-other snitable material are interposed Vbetweenl said 'members and the wall l0 to form la more eflicient clamp and-seal.`

Thebody portion 16 is formed with a cen- Y e5 forwardly.-f The rearendof this opening is aligned with the opening 2lformedby ring f' 4orvinner member 15. The kforward'end of Said opening 20 terminates in anoutwardly seatedclosure member or plate-14', the edge of which istapered as indicated Vat124 in order :to form av snug t: y

Thisclosure plate 14 is'iforin'edv with and' integral radial arm or extension V2 5 whichis adapted'to lie flat againstthe face'of member l' 14 vwhen said closure plate occupies` closed position (see Fig. 3).V A zhorizontally diS- posed bolt 26 is mounted in bore 27 formed in the upperportion ofmember 17 andy the for-4 80 Vwardend of said bolt is reduced a-'nd screwthreaded as indicated at Q8 and engages extension25. The inner end`29 of said bolt is enlarged in diameter and has b'earin'gin tu'- b'ular extension 30' which projects from said body portion inwardly and outwardly through opening'formed in ring or inner member 15.` The bore 27 is of "substantially the samediameter as the inner end 29 andLis 31, one endV of whichbears against-'the outer end of Lsaid bore adjacent to flange1`4 while the otherA end thereof bears against theshoul- 95 der 34 'formed bythe junction of the shank Qaandthe` enlarged inner end 29. Thus the f 5'tension of saidspring serves to hold thef'bolt inward or retracted'positionjthereby holdingy the `closureplat'e to its seat in the body 100 f portion and closing theopening 20. A handle Vor thumb piece 'is'secured to end 2S andV provides meanswhereby said bolt can be manually operated-to open andvclose said closure plate.

Thefto'n '26 isf slidably md revolutiy mounted in position. When it is desired to forced open by means Voit tools lappliedto the lopen the gun port Athebolt is pressed for? wardlyfso as toY unseat 'saidclosure plate' whereupon said bolt ispa-rtially rotated to move said closure plate to oneside clear ot theopening 20, To close said opening-'said bolt is rotated to .bring the closure plate in register with the seat 21, whereupon theten- 4 sionlotthe spring-:seats the closure plate.

`VThe outer faceofthis closure plate is formed smooth andy is `devoidfiof any vprojections or recesses so that said closure plate cannot be Aouter-face thereof.

*Y The countersunk t portion of "the `closure Y Aplatefwhen closed prevents accidental displacement thereof. The coiled spring is of predetermined strength so that sufficient ftorce has to'be applied to the thumb member ol'hwing nut Y35. to'unseator move the plate Y beyondv theplane of kthe seat before said clollsure plate can Abe moved laterally.
